Earth Space Science

In late 2017, scientists at a Hawaiian observatory glimpsed an object soaring through our inner solar system, moving so quickly that it could only have come from another star. Avi Loeb, Harvard’s top astronomer, showed it was not an asteroid; it was moving too fast along a strange orbit, and left no trail of gas or debris in its wake. There was only one conceivable explanation: the object was a piece of advanced technology created by a distant alien civilization.

Aliens ripped a hole above Earth, arriving with a massive space station. I sorta figured we'd be enslaved to fight in their wars or exterminated for our resources. Nope. The hip-high Iglax were merchants with ugly squished faces and thick blue fur. While they weren't much to look at, they sure did have some wonderous technology.

The number-one best-selling author of The Future of the Mind traverses the frontiers of astrophysics, artificial intelligence, and technology to offer a stunning vision of man's future in space, from settling Mars to traveling to distant galaxies. Formerly the domain of fiction, moving human civilization to the stars is increasingly becoming a scientific possibility - and a necessity. Whether in the near future due to climate change and the depletion of finite resources or in the distant future due to catastrophic cosmological events, humans will one day need to leave Earth.

For anyone who has ever looked up at the stars and wondered what it all means, Issac Asimov’s Guide to Earth and Space is indispensible. Issac Asimov’s gift for popular and entertaining exposition has never been better deployed, with his succinct answers to the most intriguing questions about planets stars and galaxies. What are quasars? How was the Earth formed? Puzzled by pulsars? Perplexed by the Big Bang? Bewildered by black holes?

Humanity pushed its way to the stars—and encountered the Gbaba, a ruthless alien race that nearly wiped us out. Earth and her colonies are now smoldering ruins, and the few survivors have fled to distant, Earth-like Safehold, to try to rebuild. But the Gbaba can detect the emissions of an industrial civilization, so the human rulers of Safehold have taken extraordinary measures: with mind control and hidden high technology, they've built a religion in which every Safeholdian believes, a religion designed to keep Safehold society medieval forever.

With the continuing failure of the Oversoul, the artificially intelligent guardian computer of the planet Harmony, the human colonists have begun to repeat the devastations of war and conquest wrought on Earth. To repair itself and avert disaster, the Oversoul has called a group of 16 refugees from the fallen city of Basilica to a hidden, abandoned spaceport where the ancient starships lie.

Betrayed by allies. Beset by new foes. Earth faces its darkest hour since the Xaros invasion. The Toth come to the solar system with a fleet of warships, and they demand the only tool that can rekindle the human race. It falls on Marine Lieutenant Hale to negotiate a pact that will save the human race at the cost of its soul - or start a war with a race of alien predators.

For millennia, the planet Harmony has been protected by the Oversoul, an artificial intelligence programmed to prevent thoughts of war and conquest from threatening the fragile remnant of Earth's peoples. But as the Oversoul's systems have begun to fail, a great warrior has arisen to challenge its bans.

A menacing wasteland. A destructive new weapon. A planet on the edge of catastrophe. Sheriff Duke can’t rest. There’s no time to slow down. The threats are unending. The enemy unyielding. If he wants to stop the apocalypse, he’ll have to cross a treacherous wasteland where the cannibals and murderers are the least of his worries, and the creatures infesting the landscape aren’t the most dangerous thing in his path. The race is on, the doomsday clock is counting down, and if he fails it will be more than his wife and child that are caught in the fallout. It’ll be the world.

The basilisks. Giant serpents from deep space. Their true name is unknown. Their homeworld is cloaked in shadow. But one thing is certain: They're killers. And they vow to kill us all.

With the invention of faster-than-light travel there is nowhere that humanity cannot go. New worlds are discovered, but with them come new dangers. At the heart of the discovery is the Fermi, mysterious beings that have survived on alien worlds for longer than humanity has existed. But now the Fermi are awakening, and they do not seem pleased to find humans in their midst. But for Lakshmi Nayak and the crew of the Fighting Chance, danger is a lot closer to home. Their search for answers will take them to places, and worlds, they never expected.

For Sheriff Duke, the danger has reached the final countdown. Captured, tortured, beaten, but undefeated, it’s 60 seconds to midnight, and the only way to save his wife and daughter is through the fugitive he left home to hunt. But the real enemy isn’t what they seem, and the history of the forgotten Earth is about to be rewritten. Will any of it matter if there’s no one left to read it?

In the final book of his astonishing career, Carl Sagan brilliantly examines the burning questions of our lives, our world, and the universe around us. These luminous, entertaining essays travel both the vastness of the cosmos and the intimacy of the human mind, posing such fascinating questions as how did the universe originate and how will it end, and how can we meld science and compassion to meet the challenges of the coming century?

Some see dust as dull stuff, useless at best, and sneeze-inducing at worst. But in the hands of writer Hannah Holmes, dust becomes a dazzling and mysterious force. As Holmes says, dust is a messenger, and air is its medium. And by the end of this fascinating journey through The Secret Life of Dust, we cannot help but agree.

The Iglax Star Empire’s tried twice now to throttle this upstart species before they could expand beyond Sol. They once used humans for cheap mining, cheap labor, and cheap laughs. But with each attempt, humanity’s gotten stronger, spread across more star systems, and found new allies. Now the Iglax are preparing for war.
